Display Device Setting History Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices for image forming apparatuses face challenges in improving user operability when displaying and managing setting history information, leading to difficulties in selecting desired setting information due to overcrowding, confusion, and reduced viewability.
Innovation Solution
A display device with one or more processors and memories that store setting information as setting history, featuring a display with a first region for listing setting history information, a second region for displaying selected setting information, and a reception button to instruct the display of a setting screen based on the selected history.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If setting history information is displayed in a compact format to show more items, then the quantity of displayed information increases, but the viewability and identification of individual settings deteriorates
Solution Approach 1:
The display is divided into multiple pages, with each page showing a limited number of setting history items (e.g., 5-10 items per page). Users can navigate between pages to view different sets of history information, ensuring that each individual item remains clearly visible and identifiable while the overall quantity of accessible information is significantly increased.
Solution Approach 2:
The patent introduces temporal navigation (past/future pages) as an additional dimension for accessing setting history information. Instead of crowding all information into a single view, the system organizes information across multiple temporal pages, allowing users to navigate through time dimensions to access different sets of history data while maintaining clear presentation of individual items on each page.
2Ease of operation
If all setting history information is displayed on a single screen, then accessibility is improved, but the display becomes overcrowded and confusing
Solution Approach 1:
The setting history information is segmented across multiple pages, with each page displaying a manageable subset of items. This segmentation prevents visual overcrowding while maintaining ease of access through intuitive page navigation controls that allow users to move between different time periods or sets of history information.
Solution Approach 2:
The display system dynamically adjusts between showing current settings and historical settings based on user navigation. The interface becomes dynamic as users can switch between different time periods, with the display adapting to show relevant information for the selected time period while maintaining a consistent and non-confusing layout structure.
3Measurement precision
If detailed setting information is displayed for each history item, then identification accuracy improves, but the display area required increases
Solution Approach 1:
Detailed setting information is segmented and displayed only for the currently selected or active history item, rather than simultaneously displaying all details for all items. This allows the interface to maintain high identification accuracy for the focused item while keeping the overall display area efficient by showing summarized or minimal information for other items in the list.
Solution Approach 2:
The display applies different levels of detail to different parts of the interface: the currently selected history item receives detailed information display for precise identification, while other items in the list display only essential or summarized information. This local quality differentiation optimizes both identification accuracy and display area utilization.
Data Source
AI summary
A display device includes one or more processors, one or more memories that store setting information of an executed job as setting history information under control of the one or more processors, and a display. The one or more processors display in the display a first display region for displaying a list of setting history information stored in the one or more memories, a second display region for displaying the setting information based on the setting history information selected by a user from the list display, and a reception button for receiving an instruction to display a setting screen of a job in which the setting information based on the setting history information selected by the user is employed.
